DescriptionHandwritten notebooks and loose pages for a planned genetics text by Hermann J. Muller and Edgar Altenberg while in graduate school at Columbia University, 1912, which was unpublished. "This is the original notebook of Muller's... for the projected text with Altenberg ~1913-1914 which they abandoned when Morgan began work on the 'Mechanism of Mendelian Heredity.' Altenberg turned down an invitation to write a chapter but Muller wrote 3 or 4 chapters for Morgan. Muller quoted from this early effort in his 'Collected Works.'"
